Sprite Sheet Creator addresses the need for efficient generation of 2D game assets, specifically playable characters and maps with associated sprite sheets and backgrounds. Powered by fal.ai, it targets game developers and pixel art creators seeking an AI-assisted workflow to streamline asset production, offering distinct modes for side-scroller and isometric game types.

How It Works

Leverages fal.ai models (Nano Banana Pro, GPT Image 2) for AI-driven character generation from text or images. It renders sprite sheets with consistent character identity across frames and generates matching backgrounds. Side-scroller mode produces 3-layer parallax backgrounds, while Isometric mode creates a top-down world map. Bria handles background removal for assets.

Quick Start & Requirements

Install dependencies using npm install. Requires a FAL_KEY environment variable set with your fal.ai API key. Run the development server with npm run dev and access the application at http://localhost:3000. Obtain API keys from https://fal.ai/dashboard/keys.

Highlighted Details

• Features two distinct game modes: Side-Scroller (walk, jump, attack, idle sheets, 3-layer parallax backgrounds) and Isometric (RPG) (walk, attack, idle sheets for 3 directions, top-down world map).
• Supports character generation via text prompts or image-to-pixel-art conversion, ensuring consistent identity.
• Includes robust editing tools: frame extraction, adjustable grid dividers, animation preview (FPS), per-sprite scaling, layer positioning, and map resizing.
• Utilizes fal.ai's Nano Banana Pro and GPT Image 2 for generation, and Bria for background removal.
